US Consumer Prices Rose 3.7 Percent in September as Gasoline Drove the Monthly Increase

US consumer prices increased 3.7 percent in the twelve months through September, up from 3.4 percent in August, the Bureau of Labor Statistics reported on October 14.

The Consumer Price Index rose 0.6 percent on a seasonally adjusted monthly basis. Gasoline prices jumped 9.1 percent and accounted for more than half of the overall monthly increase. Energy as a whole rose 5.2 percent in September and 20.4 percent over the year. Core prices, which exclude food and energy, rose 0.3 percent for the month and 2.6 percent over the year, up from 2.4 percent in August.

The annual rate exceeded the 3.6 percent consensus forecast. Shelter costs contributed to the core reading with a 0.4 percent monthly rise. Food prices were essentially flat for the month. The gasoline surge follows elevated crude prices linked to ongoing conflict involving the United States and Iran that began earlier in the year. Average national pump prices stood above $4 a gallon for an extended period.

The report is the final major inflation snapshot before the November midterm elections. Wage growth has lagged the headline rate for several months. Treasury yields rose after the release as traders adjusted expectations for Federal Reserve policy. A rate increase later in October remains possible if subsequent data do not show cooling.

Energy commodities rose 35.3 percent over the year, with fuel oil up more than 70 percent. Core goods were mixed, while services excluding energy continued to show moderate gains. The September figures confirm that energy remains the dominant driver of the recent acceleration even as underlying inflation sits above the Federal Reserve’s longer-term target.

Households face higher costs for transportation and heating as the winter season approaches. Businesses that rely on diesel for logistics have reported elevated operating expenses. The BLS release provides the official breakdown by category and will be incorporated into revisions of real wage and real spending estimates for the third quarter.

Further monthly reports will show whether the gasoline spike persists or eases if crude prices stabilize. The core rate’s move to 2.6 percent indicates that non-energy prices have not fully returned to pre-conflict levels. Policymakers will weigh the data against employment figures and financial conditions when deciding the next policy step.
